IMPROVEMENT IN WOOD PAVEMENTS.

Specification forming part of 4Letters Patent No. 126,776, dated May 14, 187.2.

.exact'description thereof, reference being had' to the accompanying drawing and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in the construction of a wood pavement made of saplings, of suitable circumference, cut into blocks of the required length, and` provided on their sides with one or more cuts or gashes so that whenl the blocksare set on end to form the surface of the pavement, and the concrete, sand, crushed stone, gravel, and other materialis lled in between the adja cent blocks, the material will` also iill into the p recesses in the sides ofthe blocks and hold the blocks down tothe earth and hold them together, as more fully hereinafter set forth.

In the drawing, Figure l represents a plan view, and Fig. 2 a section of the pavement.

A A represent the blocks which form my pavement. These are cut from small trees or saplings Vwith a diameter of generally from about four to ten inches, and are eut of a length varying from about five to six inches.

I do not, however, confine myself to the diameter or length of these blocks.

Upon the periphery yof each block VI make one or more incisions, a, a short distance into the side. This cut may be made on any one side of the block, or on several of its sides, and at any place on the periphery thereof, and may be-of any shape or by any means preferred.

Probably, the simplest manner ,of so making them would be to place two sides of the blocks in contact with a circular saw until the cut is made deep enough for the purposes desired. After the blocks are completed they are set on end on a suitably-prepared base, so that their sides are near together. The spaces between are then filled in with concrete, gravel, sand, broken stone, brick, or other suitable material, B, and so packed down that the material will iill and pack in the recesses in the sides of the blocks.

The advantages of this mode of constructing a Wood pavement are obvious. It can be made of small timber which is unit to be made into lumber. It gives a sure and good foothold for horses in every direction, and the recesses in the sides of the blocks becoming filled in with the packed material, this becomes quite solid and holds the blocks in their places, thereby preventing them from turning or working up or down and forming an uneven surface.

In some cases I may make a cut, b, in the top surface of the blocks for additional foothold, if desired.

I am aware that a wood pavement composed of a series of round blocks, made in conic frustum form with'circumferential grooves near their centers and set upon end, alternating the large and small ends down, is not new. My pavement is made of small timber of natural circumference, and so cut into blocks as to allow the tops and bottoms to be as near the same size as possible, and are provided with cuts or gashes, irregularly made in the sides, so that the concrete when filled in will take into the blocks and effect-ually hold them down and prevent their being rotated in their places.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The within-described pavement, composed of the blocks A of natural circumference and provided with one or more irregularlycut gashes in their sides, the blocks set on ends, and the spaces between the blocks iilledA in with suitable material that will take into the gashes, all substantially as set forth.

In testimony that I claim the foregoing I have hereunto s et my hand this 9th day of April, 1872.

Gr. A. BEIDLER.
